This rear height control air suspension
controls the vehicle height depending
on the vehicle driving conditions. Select
your desired height among the “HI”
(high), “N” (normal) and “LO” (low)
modes with the height select switch.
(a) Vehicle height modes
“N” (normal) mode—
The vehicle height in this mode is stan-
dard. Regardless of the number of occu-
pants or the luggage loading condition, the
vehicle height is always automatically ad-
justed to a fixed height in this mode while
the engine is running.
This mode is suitable for ordinary driving.
“HI” (high) mode—
The vehicle height is about 40 mm (1.6
in.) higher at rear than the “N” mode
height.
This mode is suitable when driving on the
bumpy roads and through water.
However, when the vehicle speed exceeds
about 30 km/h (19 mph) or over in the
“HI” mode, the “N” mode is automatically
selected.
CAUTION
The “HI” mode should be used for
severe off- road driving condition
only. Because the vehicle’s center of
gravity is higher in this setting, the
vehicle may become unstable when
turning abruptly, resulting in accident.
“LO” (low) mode—
The vehicle height is about 20 mm (0.8
in.) lower at rear than the “N” mode
height.
This mode allows you easy access to the
vehicle (getting in and out) and easy load-
ing and unloading operation.
This mode is available when the vehicle
speed is under about 12 km/h (7 mph).
NOTICE
Use the “LO” mode when the vehicle
is stopped. Otherwise, when the ve-
hicle speed exceeds about 12 km/h (7
mph), “N” mode is selected automati-
cally. So be careful when you drive in
any place where the overhead height
is limited.
(b) Vehicle height mode changing con-
dition
To change the vehicle height, it is neces-
sary to meet the following conditions.
The engine should be running.
The height control “OFF” indicator light
should go off.
